A couple of observations based on having watched new shares enter the market on many different occasions:
If for some reason those driving the trading want the volume to be higher, they arrange for the selling broker to short shares rather than just selling them directly. This basically doubles the volume from what it would otherwise be because he shorts and covers in separate trades.
The larger volume days near the bottom are usually pre-arranged buyers getting loaded, especially when the volume at a particular price level exceeds the quantity shown on the bid prior to the dump.
Much of the trading volume is flippers trying to protect their cost basis. If the price doesn't go up, they dump on the bid and try to buy back a tick lower, but if it doesn't drop, then they buy back in again at the same price.
This same technique is used by the professional traders. They'll wipe out the bid to keep the price in check while they accumulate at that price level. This may have happened yesterday. There was good bid support at 6, and when the 7's started getting hit, they wiped out the bids at 6 and left less than 100k showing for hours while they took everything offered at 6, and then even grabbed 10M or so of the 7's later in the day.
One other thing I've observed is that the sp is often irrational to retail. When the message boards are totally negative and shareholders are in despair is when the sp goes up, contrary to any logic.
Last of all, don't fight the trend, and right now, the trend appears to be UP. The powers that be seem to want it higher, so go with the flow....
Have a nice day (although it's already late for you). ;-)
